Abstract
A fuel cap is disclosed which is particularly effective in not only addressing the problem of permitting reliable relief pressure, but also in providing adequate sealing for varying environmental conditions, such as extreme pressure, temperature and swelling. The cap includes a plug member having at its lower end an elastomer sealing member integrally molded into a groove that extends around the periphery of the cap. Moreover, the sealing member is uniquely oblong shaped such that with increasing internal pressure within the tank the sealing member is deformed such as to assist in the sealing.
